You're expected to OFAC all beneficial owners on your certification. If you have an individual with a positive match to the OFAC list, and that individual owns 50%+ of your legal entity, the legal entity will also be reported to OFAC as a positive match. Conversely, if you get a positive match on an entity, and you're aware of an individual with 50% or more ownership of that entity, the individual is also reported as a positive match and funds frozen as applicable. That's the value of obtaining ownership %.
